Details view gets in the way for Flamegraph

1. Record some data with the QML Profiler.
2. Show the Flamegraph tab.
3. Hover the mouse over some entity.
   A tooltip-like details view will appear in the upper left corner of the flamegraph view:
   
   If you want to point a something beneath this window, you can't see where you're pointing. You can't move away that window since as soon as you try, it will disappear.

This details view should be shown somewhere where is does not annoy the user.
